What's a mutex? I answered it wrong. She went on to next question. I asked the answer. When she said "mutually exclusive" I said I can explain what mutually exclusive means. She said never mind and wasn't interested in letting me explain the definition. Odd to me that they wanted someone with a rote memory rather than an engineer who knows how to think.

Describe the internals of an ADC. What is a SMPS? What is an LDO? Where does loss come from in each device?? Why would you choose one over the other? Why do electronics performance degrade with an increase in temperature? Describe how you would test a water bottle.
